衝器。[Claims for Utility Model Registration] (1) Between the inner cylinder of the hydraulic shock absorber and the rod guide having an insertion part tightly inserted into the inner cylinder and a flange part having a larger diameter than the insertion part, In a hydraulic shock absorber designed to sandwich the inner circumference of a ring-shaped check valve that opens and closes an oil communication hole formed in the flange of a lock guide, an annular spacer is provided between the end face of the inner cylinder and the rod guide. A gap is provided between the spacer and the rod guide along a direction parallel to the axis of the inner cylinder, and the gap is slightly smaller than the thickness of the inner circumference of the check valve. A hydraulic shock absorber characterized by clamping the inner circumference of a valve. (2) The spacer is sandwiched between a stepped portion formed on the rod guide and the inner cylinder, and the check valve is attached to the outer periphery of the stepped portion while being sandwiched between the spacer and the rod guide. A hydraulic shock absorber according to claim 1 of the utility model registration claim. (3) The spacer is formed into a cylindrical shape consisting of a large diameter part and a small diameter part, and is held between an inner cylinder and a rod guide, and the check valve is arranged on the outer periphery of the small diameter part and has a large diameter part and a large diameter part. The hydraulic shock absorber according to claim 1, wherein the hydraulic shock absorber is mounted in a state where it is held between the diameter portion.
